the simulation kept track of the variables and automatically recorded data on object displacement, velocity, and momentum. if the trials were run on a real track with real gliders, using stopwatches and meter sticks for measurement, how might the data compare? check all that apply.
this- there would be variables that would be hard to control, leading to less reliable data
- the data would be just as valid if it were recorded with a stopwatch.
this- meter sticks may lack precision or may be read incorrectly.
this-  real glider data may vary since real collisions may involve loss of energy.
this human error in recording or plotting the data could be a factor.
- controlling real glider velocities by hand would be just as accurate as simulation controls.

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
